RE: 3mmtoc53cc vs dl50
There's not a lot of long term history out there on either of them, but it seems to me that the DL50 is cheaper priced, lighter in weight, has better power to weight ratio, is extremely user friendly and just generally seems to be making more waves in the R/C community than the other ... so I'd say the DL50 is the choice. I considered the two, and bought the DL50.
